Gary Jules and Michael Andrews - Mad World

Recorded for the Donnie Darko sountrack, Gary Jules and Michael Andrews' haunting, stripped-out cover of Tears For Fears' classic was originally released in April 2002 alongside the film.

However, it wasn't until December 2003, when the slow-burn success of the movie had reached the mainstream, that Mad World took the festive top spot. Number 1 in the UK and Portugal, the song didn't have nearly as much impact across the Atlantic, failing to chart on the Billboard 100.
